Question

In January, a store sold a pack of collectible cards for $1.75. In February, they sold the same pack of collectible cards for $1.89. What is the percent of the increase?

Answer 1

8%

Explanation:

Step 1: Find the difference (increase) between the two costs

`\$1.89 - \$1.75\\\\= 1.89 - 1.75\\\\= 0.14`

Step 2: Divide the increase by the original cost

`0.14 / 1.75\\\\(0.14)/(1.75) \\\\= 0.08`

Step 3: Convert the answer to percent

`(0.08)/(1) * (x)/(100)`

Cross multiply

`0.08 * 100\\\\= 8 \\\\= 8\%`

Therefore, 8% is the percent increase.
